Doesn 900 Mhz have a bad reputation for being a crowded band?
Maybe in the past. If you try to use your unit near a garage door opener tradeshow, you MIGHT have some trouble, but we have not seen any problems. Seriously though, 900 MHz is in use by many devices, which is why the spread spectrum frequency hopping is important. In our tests, we’ve never seen any interference despite the fact we have many 900 MHz cordless phones and 802.11 networks in the neighborhood. In rare cases where very high power 900Mhz transmitters are being used you may see some issues. However, this will not be found in civilian areas.
